There is one situation in Bonn, Germany, where the buses have their own lane (right one) and the cars are separate (left lane). The cars have a regular traffic light (red, yellow, green) and the buses have their special kind (white bars,
|). It looks like this:
The interesting thing is that the cyclist are supposed to take the bus lane, so they are on the right lane. One can see that right after the traffic light there is a dashed line parallel to the road that marks the bike area on the road.
The traffic light obviously aids the buses and cars merge again to a single lane. As a cyclist, I am not really sure what to do:
I could abide the car traffic light. It is the traffic light that I have been taught to read in school (elementary school, actually) and is the official one for car drivers as well. However, when the car traffic light is green, I have a harder time merging with the cars.
Use the bus traffic light because it is in my lane. It make also most sense since the traffic light is for merging the two lanes. But I cannot really read the traffic light, I just assume that the three lights correspond to red, yellow, and green. If a bus was right behind me, he would have to pass me if I waited for the car traffic light to switch to green again. This doesn't make any sense, I should just free up the bus/bike lane.
Ignore both lights. In every case I can just slowly merge with the car lane as I see fit. Usually one of the lights is on “Go”.
Every time I pass this place, I am a bit uneasy whether I am doing the right thing. I just carefully watch for traffic and merge with the car lane when there aren't any cars around. I'd like to know what the correct behavior for this situation would be.
